B3 will reduce the FRC Round Lot in electronic calls from 100 to 10 contracts by matching the regular trading session lot to the call lot. This improvement is aimed at facilitating clients’ access to product liquidity in electronic calls. To mitigate the risk of distortion of the FRC curve in less liquid maturities, the settlement price for each maturity will be determined by the call only when there are more than 100 contracts traded in the call for the maturity in question.
